barry arnoldFrank et al,
I strongly recommend Jon Canfield's book on Cigarette Packs which answers questions such as these and many more. I'm hoping that some are still available for sale.
It has been the most critical and informative part of my recent collecting;
I now have 13 different T206 era packs, largely due to Jon's book and
helpful, generous tutelage.
best,
Barry
